Implement and Charge pump spring and cone questions.
 

I have a ported pump that has never had the hydraulic add on installed. I have been looking at the manual for the 169 hydraulic add on setup here, page 9. http://ccmanuals.info/pdf/169%20Hydr...On%20Setup.pdf So I take the implement spring out(1/32" wire), put in a new thicker spring(1/16" wire) and take the 1/32" I took out of the implement and put it in the charge relief port with a cone. So my questions are,

1- Does the spring pressure here decide the proper hydraulic pressure going to implements and charge pump?

And for me to do this I need a cone and a thicker 1/16" wire spring.

2- Can I use the cone out of another pumps implement relief and put it in my charge pump relief or are the cones different?
